To @32? whom it may eminem.'

Be it known that I, Fem'met Jess-,m1,

engineer, :L citizen of the Kingdom of Norwey, residing at St. QlepsGete 24;, Chris tierna, NorWey,-heve mveuted e new eed` useful'mrovement m Capsules for Bottlesend the ilze; end l do hereby declare theY' following to be e full, oleer, emi exeet deserlptl'on of the seme.

In the usuel bottle sealing or. Closing de vices, e capsule is placedover the bottle mouth end lts lower cerro ated edge portion is clemp'edor crimped in eneeth the upoer mouth roll. However, in devices of taiskind, it isrleeessery to use e comparatively yielding `tighteningmeterfiel smell es cork, eeeutehoue, etc., m order teeiptem periecttightness. i nowvheve elgserver, theft 'the reason for this meonvenieneeis to be sought m the feet, that, en account of the shape of the capsuleeoi'russtioes oonteeting time mouth roll durilig ,L e demping ot` theeel? t e suie, only compressive strains arise in edge materiel, so thatthe letter, es seen es the elempiegtool is removed, has e tendency toyield somewhat beek, i. e., the length ot' the clamping or crimping edge'of the eef@- suie tends te be extended. This extension must be teken upby the tightening or peek mg materiel, which therefore must Deeemparetivelythiek.

in order to -renove tins, drawback, my

I' presentzinveiition hesiter its object te pro'- vide eeeeing capsulein which during the crimping, end later on (es long es the cap sulecovers the bottle mouth), tensile strains are produced along the edge,portion, seid strains, therefore, holding seid lportion et all. times-ine state iet tension, so that the edge of the'eepsule lies no tendeneyWheteveivte be extended but, on 4the contrary, has s tercl--v eney toclamp the edge more 4 strongly -erouue- 'the bottle mouth. 'Enetightening or peekngumeteriel may, therefore, be um elastic emol of lessthickness than heretofore.

Having now ieserbed my iriventifsi *what I Gleim es new and desire teseeure by Letters Patent is z- 1 1. A. capsule for effecting sealing erelosng, ll. of bottles end the like, .having e eerrugeted erige' Whoseeerrugetioes are et seek, etage m. center e5 that, upon contractionponia beide-neck, the edge is provided Wish :i series of dovetailedprojections for the purpose of producing, inthe edge ortion, strainstending to eoik tract the sei portion around they upper mouth roll ofthe bottle.

2. A device for sealing or' Closing bottles and the like, comprising ecapsule the crimping edge of which has e plurality of projections thesides of which converge towards the center of the ce suie.

3. A device ior sealing or closing .bottles end the like, comprising a.capsule the crimp ing edge of which hes a, phireiizy of proeotions thesides of which converge towards the Center of the Capsule, the innerparte of the edge connecting the projections with euch g other beingCurved invmrdiy towards the center ofthe capsule.
